Underlayment products are the final line of defense between the home and the elements. Underlayment products help block water from the roof deck and out of the home to help prevent rot, mold, and water damage.

When used with the proper exhaust ventilation, intake ventilation products help replace the warm, humid air in your attic with cool, dry air to help protect the interior components of your roof system from heat and moisture damage. They also help keep the attic temperature closer to the outside temperature to help eliminate problems such as ice damming, which can cause premature shingle deterioration.

Exhaust ventilation helps draw air out of the attic, protecting the roofing system from heat and moisture damage. Optimally designed to work together with our VentSure® intake ventilation products, they help create a balanced flow where warm, humid air is continuously replaced by cool, dry air.
